They did a decent job with the foundation. So no leakage unless it's a lot of rain. The yard just outside the back door turns into a little pond for a day or two.
The Coop will be up from the house in the middle of the yard.
I was thinking a little up & to the right of where my son is standing.
Cute kid!
I’m guessing photo was taken out your back door and up the slope?
Everyone dealing with sloped land has to address it in some way. When you put in the coop, it needs to be level, so you can level out an area to place the coop, but might need a slight retaining “wall” of blocks, a log, something. I’ve seen some people dig out an area, line the bottom and sides with block (almost like constructing a short walk-out basement), and go from there -pretty extensive and not likely done too often! And the most common (and simple), is to build a platform/frame that is leveled, but may require some steps up into the coop for your access. In any of these scenarios, you could add drainage pipes underneath the ground to drain the water around/away. OR you can dig a shallow trench filled with gravel, on an angle to catch and divert the water flow away. Of course, you could always build your “dream garden” of stepped raised beds above where the coop would be to catch all that water and utilize it. Hardly any work at all!
